E) basal slip

Question

Quizplus · Accepted Answer

Glacial scouring by bedrock embedded in ice is erosion by abrasion. The rocks embedded in the ice act like sandpaper as the glacier moves over the bedrock, wearing away the surface and creating striations. Ablation refers to the loss of ice or snow from a glacier, accumulation refers to the addition of ice or snow to a glacier, periglacial means refer to cold regions on the edges of glaciers, and basal slip refers to the movement of a glacier along its bed due to the presence of meltwater lubricating the base.
